* bugfixes: NFSv4: Return delegations synchronously in evict_inode SUNRPC: Fix a regression when reconnecting NFS: remount with security change should return EINVAL nfs: do not export discarded symbols NFSv4.1: don't export static symbol

NFSv4: Return delegations synchronously in evict_inode

2015-03-27T16:24:36+00:00

Kinglong Mee reports that asynchronous delegations are being killed by the call to rpc_shutdown_client() when unmounting. This can lead to state leakage on the server until the client lease expires. Reported-by: Kinglong Mee Signed-off-by: Trond Myklebust

NFSv4: Append delegations to the per-client list instead of prepending

2015-03-12T16:13:56+00:00

Do so on the assumption that for most use cases, that list will turn into a more or less LRU-ordered list, and so the list traversals in nfs_client_return_marked_delegations() are likely to be shorter before hitting a candidate to return. Signed-off-by: Trond Myklebust

NFSv4: Ensure we skip delegations that are already being returned

2015-03-02T23:09:15+00:00

In nfs_client_return_marked_delegations() and nfs_delegation_reap_unclaimed() we want to optimise the loop traversal by skipping delegations that are already in the process of being returned. Signed-off-by: Trond Myklebust

NFSv4: Pin the superblock while we're returning the delegation

2015-03-02T23:09:14+00:00

This patch ensures that the superblock doesn't go ahead and disappear underneath us while the state manager thread is returning delegations. Signed-off-by: Trond Myklebust

NFSv4: Ensure we honour NFS_DELEGATION_RETURNING in nfs_inode_set_delegation()

2015-03-02T23:09:14+00:00

Ensure that nfs_inode_set_delegation() doesn't inadvertently detach a delegation that is already in the process of being returned. Signed-off-by: Trond Myklebust

NFSv4: Ensure that we don't reap a delegation that is being returned

NFSv4: Don't call put_rpccred() under the rcu_read_lock()

2015-03-02T04:23:07+00:00

put_rpccred() can sleep. Fixes: 8f649c3762547 ("NFSv4: Fix the locking in nfs_inode_reclaim_delegation()") Cc: stable@vger.kernel.org # 2.6.35+ Signed-off-by: Trond Myklebust

Merge branch 'cleanups'

2015-02-18T15:28:37+00:00

Merge cleanups requested by Linus. * cleanups: (3 commits) pnfs: Refactor the *_layout_mark_request_commit to use pnfs_layout_mark_request_commit nfs: Can call nfs_clear_page_commit() instead nfs: Provide and use helper functions for marking a page as unstable

NFSv4: Kill unused nfs_inode->delegation_state field
